Recent advances in emergency life support.

With additional international input, recent changes in emergency life support are reflected in updated guidelines for Advanced Cardiac Life Support (ACLS) from the American Heart Association and new technology in the arena of vascular access and emergency airway management. These changes will expand nurses' ability to provide advanced levels of care, even in the prehospital situation, and represent a more rigorous evidence-based approach than ever before. As early morbidity and mortality in emergency situations are frequently associated with complications associated with airway management and vascular access, recent development in these areas are reviewed along with evolution in ACLS guidelines.
